Regulatory proteins
bind to repressor



trp operon and lac
operon are two different systems: trp operon is repressible while lac operon is
inducible. Their common feature is that both have effector molecules that binds
with repressor proteins, but the interactions yield different results. In an
inducible system like lac operon, the interaction was initiated so that the
repressor protein cannot bind to the operator, while in a repressible system
like trp operon, the interaction was made so that the repressor protein can
bind to the operator.
